The importance played by mechanical engineers in motorcycle crash events investigations arises from their special skills.

Mechanical engineers work to find underlying reasons for the motorcycle accidents. The experts exhibit detailed understanding of mechanical system operation and failure modes. Their professional guidance assists personal injury attorneys in determining if mechanical system malfunction was the cause of their motorcycle accident. Using motorcycle gear breakdown data in conjunction with crash data, as well as the condition of the accident site, is critical for helping personal injury lawyers identify liable party negligence for rider injury.

The vast majority of cases are solved based upon expert technical evidence according to the team at Dennis Hernandez Injury Attorneys. The law office works with some of the best mechanical engineers in the country in order to determine liability in defective product and negligent maintenance claims.

What Do Engineers Inspect After a Motorcycle Accident?

The first stage of investigation involves the collection of all evidence documentation. Engineers collect:

The core elements of motorbikes — which are brakes, tires, engine parts, suspension system, and steering technologies.
How the vehicles and debris are lying as well as make note of skid marks and impact angles at the accident site.
Additional evidence consisting of witness statements together with traffic and digital data from the vehicles.

Engineers use photogrammetry and 3D Laser scanning for accidents reconstruction to find design flaws, maintenance issues and product failure.

What Brake Problems Do Engineers Search For?

On a motorcycle, the brakes usually fail due to its system components. Engineers look for:

Brake pads and rotors that are excessively worn.
Brake lines showing punctures or leaks.
Brake fluid that appears to be degraded, or with evident contamination signs.
ABS system that fails to function properly.

According to the National Highway Traffic Safety Administration (NHTSA), 22% of motorcycle crashes are related to a failure of the vehicle brake.

Why Is Tire Inspection Essential During a Crash Investigation?

Tire inspection plays a critical role in crash investigations based on its importance.

A motorcycle relies completely on the tires to maintain contact with road surface. Engineers evaluate:

Tread depth and overall wear.
Tire pressure levels at the time of the accident.
Evidence of blowouts, sidewall damage, or punctures.
Wheel balance, alignment, and structural integrity.

The state of the tires and service records can be used to substantiate recall claims, while revealing potential poor maintenance services.

How Do Steering and Suspension Failures Cause Motorcycle Crashes?

Motorcycle crashes due to steering and suspension system failures occur for particular reasons.

How a motorcycle responds to the commands of the rider relies on the steering and suspension systems. Engineers assess:

Fork condition and handlebar alignment.
Shock absorber
Inspection of the suspension wear status and damages along with aftermarket modifications checks.

Choppy forks and worn shocks yield less control when you have to steer in a hurry. The evidence is crucial to decide product defect or maintenance negligence responsibilities.

Can Engine or Transmission Failures Cause Motorcycle Accidents?

Yes. Motorcycles may crash due to loss of power and/or engine seizure resulting from breakdowns in an engine or transmission.

Engineers examine the engine and transmission for:

Leaking fluids or
Signs of
Transmission slipping or gear-shifting issues.
Records of improper servicing or neglect.

The power loss and engine seizure attributed to mechanical failure detection can also enable experts to demonstrate that manufacturing defects or substandard maintenance repairs exist, leading to the establishment of liability responsibility.

How Do Engineers Help Prove Legal Liability?

The documentation produced by mechanical engineers contributes as proof that often becomes key in personal injury and tragic death lawsuits. Their evidence includes:

Causation: Demonstrating the mechanical defect or failure was the direct cause of the accident.
Origin of the defect: a prompt professional examination will allow the exact source of the defects to be pinpointed and whether they are from design production or from maintenance.
Expert testimony: Translating complex failure into gentle reading for courts and juries.

For instance, the court in Hardin v. Kawasaki Motors Corp. employed expert evidence to demonstrate how steering failure resulted in a crash, resulting in a successful product liability suit.

Can Manufacturers Be Held Liable After Production?

Manufacturers may be held legally responsible for their products once they’re off production lines.

Absolutely. The motorcycle company accepts liability to pay out when mechanical engineers establish a production or design defect caused the accident. The resulting measures could be:

Product
Financial compensation.
Redesigns and updated safety measures.

We saw a total of over 1,000,000 motorcycle mechanical-related recalls in the USA alone during 2021. At Dennis Hernandez Injury Attorneys, we help find these potential hazards in the course of our investigations.

What Happens If a Maintenance Provider Is Responsible?

Maintenance neglect or failures leading to accidents leaves shops and dealerships exposed to potential liability. Engineers search for:

Records showing both incomplete data and unauthorized modifications
Fitting of substandard parts that are not in original manufacturer’s specifications.
Mishaps from shoddy repair work or overlooked safety checks

Service provider’s fault is clear when engineers identify both defective work and inspection failure indicators.

Are Motorcyclists Ever Responsible for Their Own Accidents?

Rider error is responsible for the majority of motorcycle crashes. Engineers evaluate:

Rider speed at the time of the crash.
Emergency maneuvering
Braking performance and gear use.
The use of helmets and protective gear by riders.

Riders involved in the crash who bear some fault can still obtain gain under Florida Statute §768.81. The court decides compensation amounts by considering the contributory percentage that a rider holds in the crash under the comparative negligence.

Does Standard Maintenance Help Prevent Mechanical System Failures?

Definitely. Preventative maintenance minimizes mechanical breakdowns and assists protects injury claims through showing no rider negligence. Riders should:

Check tire pressure weekly
Replace brake pads and fluids on schedule
Maintain proper alignment and suspension settings

Well recorded maintenance creates evidence to keep riders safe in courts of law.

Why Is It Important to Document Maintenance and Recall Notices?

Service records along with receipts and inspection results help establish that the rider did take appropriate steps. It’s also crucial to:

Monitor manufacturer recall notices.
Check for open recalls by going to the NHTSA’s Recall Lookup.

This is a type of evidence that shows that the rider cannot be held liable for the accident, as well as it supports product liability claims.

How Does a Motorcycle Accident Attorney Use Engineering Evidence?

A skilled motorcycle injury attorney will:

Work with mechanical engineers to conduct expert evaluations.
Present technical findings as courtroom testimony.
Prove that defects in the product directly led to the injury.

The motorcycle crash clients of Dennis Hernandez Injury Attorneys have recovered millions in dollars through this well-established legal tactic.
